'Tfieornmure 1 8 of the motor is mouned a Sleeve 19 which is jouneed `onthe eiwit perf; 12.' The seove on its inner end enixjies die commutator fso@ments 2O which are engzzged by the adjust-able brushes 2L "in order io adept the motor to machines running' in either direction the brushes 2l are of the radial type and l:we mounted on @ring '22 and project through .elongated sots 23.` The ring and biusixee may be revoh'fed a Sufioient distince with relation `to the poe pieces 24 of the `eld magnets 25 to change the polarity of said magnets and thus reverse he direction of rotation of the armature 18. The brush ring 22 ,is heid in .position by binding posts 26 Whiohexond upwardly enddownwardly through the machine ,The outer end portion of the armature The wo pani, horizontal shaft construetion end the removebleend of the arm per mits the easy removal. of vthe motor when desired. in removing the motor it is only neoessmy to remove he slore'w 7 and pull ibo ond @over 6 and theoranked portion of the v itl@ hoizontnly outwardly from the "anni Tizio easing 3G and die Leoin and die, elmenre 1.8 WH move and the remaining parts can then be pulled outwardly as the said magnets merely slid- .ably engage the surrounding horizontally extending casing part. The binding posts 26 may then be unscrewed from the brush ring parts and the said posts and ring parts be removedA v From the foregoin description it will be ASeen that the motor for driving the sewing machine may be removably positioned with in the sewing machine arm to utilize space not otherwise used and that the arm forms a rotection for the motor. i

hat I claim aS m invention is:

1. An electrically riven sewing machine, comprising atubular sewin machine head having a horizontally exten ing shaft in its upper arm portion, and an e ectric motor havin a horizontally extending armature exten ing parallel to the horizontal shaft and mounted in said upper arm portion and approximately in co-axial alinement with said shaft having a. driving connection between the armature and the shaft.

2. The combination with a sewing machine having a horizontal shaft for actuating a needle bar and a shuttle mechanism, of a motor encased within the head of the machine and having a horizontally extending armature extending parallel to the horizontal shaft and approximately in co-axial alinement therewith, and means for transmitting motion from the motor armature to the shaft at a less rate of speed of rotation than the speed of rotation of the motor.

3. The combination with a sewin machine having a tubular head provide with a horizontal shaft'. `lof a motor encased with-v in the head and extending around the shaft and having a driving connection therewith.

4. The combination with a sewing machine having a tubular head provided with a horizontal shaft, of a motor encased within the headand extending aroundthe shaft', and means for transmittingwmo*i i from the motor to the horizontal shaft at a less rate of speed of rotation than the speed of rotation of the motor.

5. The combination with a sewing machine having a tubular head provided with u horizontal shaft, of a motor with-in the head and having an, armature provided with a tubular shaft through which the horizontal shaft extends, and a geared connection betven the tubular shaft and the horizontal s a t.

6. The combination with aA sewing machine having a tubular head rovided with a horizontal two part shaft, o a motor within the head and havin an armature rovided with a tubular s aft through which the horizontal shaft extends, and a red connection between the tubular sha t and the horizontal shaft for transmitting motion from the motor to the horizontal shaft 'at a l less rate of speed of rotation than the speed of rotation of the ,armature 7. The combination with a sewing machine having a tubular head provided with a horizontal shaft, of a motor within the head and having an armature provided with a vtubular shaft through'which the horizontal shaft extends, a pinion mounted fast i on the tubular shaft, a counter shaft mounted in the head, a gear wheel `journaled on the counter shaft and in mesh with the pinion, said fear wheel having a pinion pro3ecting there rom, and a gear wheel mounted fast on the horizontal shaft and in mesh with the last mentioned inion.

8. The Combination with a sewin machine having a tubular head provide with an end opening and a removable end portion therefor, of a horizontal shaft journaled in the tubular head and the removable end portion, an electric motor within the tubular head and having an armature provided with a tubular shaft through which thehorizontal shaft extends, said motor being removable throughl the end opening, and means for transmitting motion from the armature shaft to the horizontal shaft at a less rate of speed of rotation than the speed of rotation of the armature shaft.

9. The combination with aegewing machine having a tubular head rvided `with an end opening and a removable end portion therefor, of a horizontal shaft journaled in the tubular head and the removable end por tion, an electric motor withinthe tubular head andhaving an armature provided with a tubular shaftthrough which thc horizon-q tal shaft extends, said motor being removable through the end o ening, a pinion mounted fast on the tubu ar shaft, a co nter shaft mounted in the head, a gear wh l journaled on the counter shaft -and in' mesh with the pinion, said gear wheel having a pinion projecting therefrom, and a r wheel mounted fast on the horizontal and in mesh with the last mentioned pnion.

10. The combination with 'a sewin ma- Y chine having a tubular head provide with tal shaft extends, said motor and Va, portion of the horizontal shaft being""remov abl'e through the end opening, and a -train of gears connecting the tubular shaft to the horizontal shaft for transmitting motion to the horizontal shaft at a lees r te of speed of rotation than the speed'of ro 'ation of the tubular shaft.
